At the end of my radiation I started having pain that I attributed to a tooth that needed a root canal, but 2.5 months later (and after that root canal), the pain continues. The endodontist squeezed the masseter muscle (muscle that closes the jaw) and it was very painful, so she thinks it's the muscle. My radiation oncologist doesn't think it's radiation related although she won't see me in person and only speaks to me through her nurse. Just wondering if anyone else experienced jaw (muscle?) pain post rads and what, if anything, can be done. She won't prescribe pain meds and never went over any exercises although I've heard people talk about jaw and neck exercises here?

Thanks for any input. I can't sleep, or eat solids, the pain is pretty intense.
